HANG-EB FOR INSULATOR CHAINS AND THE LIKE.

Application filed. Ianuary 25, 19%, serial 1T0. 688,363, and in Germany December 7, 1923.

This invention relates to a hanger for insulator chains, cables and the like, which may also be employed for connecting the ends of insulator chains, cables and like structures.

I am aware that hangers, clamps and similar devices have been employed for this purpose. In these structures it has been customary to employ a nn'ilti-part body member adapted to receive the ends of the members to be supported, and devices whereby the parts of the multi-body members are normally connected to one another. lVhen these connecting devices become loose the parts of the body member tend to separate, and when sufficiently separated permit the insulator chain, cable or other device supported, or the ends of the cable to fall or part from one another, thus rendering the hanger or coupling entirely inoperative. The object of my invention is to overcome this diiiiculty, and in doing so I provide a hanger which is preferably made in two parts adapted to be so asso ciated with each other that the parts are maintained in their associated relationship, if necessary, solely by the tension exerted in the support of the insulator chain, cable or other device with which the hanger is employed, as will be hereinafter more particularly described.

In the drawing Fig. 1 is a side elevation of one of the parts of the hanger made in accordance with my invention.

Fig. 2 is a front elevation of the same.

Fig. 3 is a side elevation of the other part of the hanger.

Fig. 4 is a front elevation of the same.

Fig. 9 is also an elevation showing the hanger employed for supporting a cable, and

Fig. 10 is a section on line 10-10, Fig. 6.

Referring to the drawing it will be seen that in carrying out the invention the hanger comprises a body member which is made in two parts. One of these parts is indicated at a. In the front elevation this part is preferably rectangular, and at one end 0. At one end this body member 6 is also provided with an enlarged portion. Z), which is interiorly recessed as indicated at 7. The enlarged end of the body portion is provided with extensions d, having a recess (17 therein, and terminating in a lip d. The extension cl of the enlarged end of the body member Z is recessed as indicated at (F, and the inner surfaces of the lips d2 are adapted to conform with the surfaces of the cutaway portions 0 at the enlarged end of the body member a. At the opposite end the body member 6 is provided with an aperture corresponding with the aperture a in the body member a.

The width of the recesses 03 is substantially the same as the thickness of the ribs 0, and the boss 0 is adapted to extend into the recess d In asembling the parts therefore of the hanger the ribs 0" enter the recesses d; the inner faces of the lips (Z lie against the outer face of the cut-away por' tions 0, and the boss 0 enters the recess l he hanger also includes a headed bolt. The shank of the bolt is indicated at c, and the head thereof at c. It will be under* stood that the other end of the bolt may be an eye or any other suitable structure. The shank of the bolt is adapted to pass through the recess ri and the head thereof to lie in the recesses f and f.

From the foregoing it will be noted that the head of the bolt when the parts are assembled bears against the walls defining the upper portions of both the recesses f and f, making it impossible to separate the parts when there is any tension applied to the bolt without first relieving this tension; when the tension is relieved the head of the bolt may be shifted suiiiciently far to move the body member a longitudinally relatively to the body member 5 so that the ribs 0 will clear the recess d, when the parts of the body member may be separated.

As illustrated in Figs. 8 and 9 the bolt 6 may be connected to a suitable series of insulators, and a pin 72, may be employed for connecting the hanger to a support 9 for a cable 9, or other similar structure.

It will now be apparent that irrespective of how loosely the pin it may connect the parts of the hanger to the able support the parts oi? the hanger cannot become separated as long as there is tension applied to the head of the su imorting bolt.

I claim as my invention:

A hanger -tor insulator chains and the like, comprising a two part body member, each having a recess which when the parts are assembled provides an interior space therein, a headed bolt passing into the body member, and the head thereof lying in the said space, longitudinally disposed ribs on one of the said body members, an extension terminating in lips on the other body memher, there being recesses in the said extension'adapted to receive the longitudinally disposed ribs, and there also being a cutaiay portion on the first said body member to receive the said lips in Which the said extension terminates whereby the said parts are sliiittable longitudinally to separate the same, and While tension is applied to the bolt the parts of the body member are maintained in their associated relationship.

In testimony, that I claim the foregoing as my invention 1 have signed my name this, Slst day of December, 1923.
